    Rules can require miners to use a certain minimum mining width in calculating mining reserves that are wider than the veins to be mined, so the ore is diluted by waste rock in the calculation. But in practice, sometimes the veins are very distinct and separate from the host rock very easily, and it's possible to take only the rock
